坪床的构造坪床构造合理与否直接关系草坪品质和寿命,因此对构成坪床的材料标准,相关的物理特性、化学参数有比较严格的要求。华东沿海地区气候的温暖湿润决定了经践踏的土壤更易板结,从而造成草坪缺氧死亡。本坪床(温州体育中心足球场)构造方案吸取了日本、西欧等国构造坪床最新技术要求,同时结合本地区的具体实际。下面就坪床构造作具体介绍: 1.草坪坪床的含沙量为85％,其它添加剂(沸石、基肥、土壤改良剂按一定比例混合组成)为15％。(见表) 草坪排水系统 (1)地表排水:在构造坪床时保证0.3％的散水坡度和坪床表面均匀的平整度,在播种前全场滚压结实。 (2)渗漏排水:在地表下作散水层,积水从坪床的江沙层渗漏到卵石层和碎石层,再汇流至周边的排水沟。这种排水结构
Ping bed structure Ping bed structure is reasonable or not directly related to lawn quality and life expectancy, and therefore constitute a flat bed material standards, the relevant physical properties, chemical parameters have more stringent requirements. The warm and humid climate of eastern China coastal area determines that the trampled soil is more easily knotted, resulting in the death of lawn hypoxia. The construction plan of Pingping (Wenzhou Sports Center Football Stadium) draws on the latest technical requirements for the construction of flat beds in Japan and Western Europe, and at the same time combines the actual conditions in the region. The following describes the structure of the flat bed for a specific: 1. Turf Ping bed sediment concentration of 85%, other additives (zeolite, base fertilizer, soil amendments mixed by a certain percentage of the composition) of 15%. (See Table) Lawn Drainage System (1) Surface Drainage: Ensure that 0.3% of the bulkhead slope and flatness of the surface of the bedding bed are formed during the construction of the bedding bed. (2) seepage drainage: make the surface of the subsurface water, water stagnant from the bed of the sand layer to pebble and gravel, and then converge to the surrounding drainage ditch. This drainage structure
